Default 883 Power

Does anyone know what the power of the 883 engine in the iron is and how much more could be gained by fitting short shots, filter and fuel pack ?

These numbers vary, but stock is right around 45 HP if I remember right. I don't know how much you would gain for certain, but changing exhaust and intake usually nets about 10%.

If you change the pipes and air cleaner, with the proper adjustment to the fuel delivery system, you can expect around a 10% increase in horse power, and around 12% increase in torque.

After I did that to my 883 I was putting 53 horse power to the rear wheel.
